CIA360MODS teaches you how to change the LED colors on your XBox 360 power brick. You need pliers, tweezers, a screwdriver, a soldering iron and smds. Unscrew the screws from the power brick and then take out the fan from inside. Follow the schematics and use the tweezer to grab the smd. Solder your new smd where the old one was. If you remove the green one, you can add a blue one instead and only that color will change in the power brick. Remember to be careful when doing soldering and keep the appliance plugged off.
